Unity Hub Error "ENOSPC: no space left on device" when trying to install editor

I'm on arch linux.
I deleted an editor and wish to reinstall it. Trying to reinstall it gives me:
ENOSPC: no space left on device

I deleted the UnityHub temp files in /tmp but did not work

 

I unmounted temp and was able to reinstall the editor. But now I can't install any components.

 

I want to test Unity on Manjaro Cinnamon Linux and experience the same issue. Unfortunately, I cannot unmount tmp, cuz it's used by the desktop. As soon as I unmount, I get kicked out of the desktop.

 

Hello! I have the same issue on fedora 32
some log

By default installation fedora, you have 3G /tmp folder and unity hub dowload can't dowload image. i fix it by increase /tmp folde size

sudo mount -o remount,size=10G,noatime /tmp

 

how did you increse it ?
